Abstract: A grille shutter control device of a vehicle includes an encapsulation structure covering an engine, a grille shutter provided at an opening formed at a front wall portion of the encapsulation structure, an actuator configured to move the grille shutter to open/close the opening, and a controller configured to control the actuator. The controller determines whether or not heat damage occurs on a related component relating to the engine upon key OFF, closes the grille shutter upon key OFF in the case of determining that the heat damage will not occur, and opens the grille shutter upon key OFF in the case of determining that the heat damage will occur.
